    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

prefixing any number with 0, and javascript interpret it as octodecimal (base 8) jist like prefixing with 0x nd javascript interpret it as hexadecimal (base 16)
u/Odog8

100% worst js feature
u/danny@hille.dk

It's a C language feature that bleed in Java, and from Java into javascript
u/Odog8

ah, didnt know that, neat. Still frustrating imo
u/New_Core

there is 0o for octal.. if use just 0 and accidently have a 8 or 9, it becomes a normal decimal while 0o will throw an error. as said before, you have 0b = binary 0o = octal 0x = hexa
u/rodrigo.siqueira

oh no, 078 throws "78" and 077 throws "63".
u/neimad

077/078 is not a really a gotcha. It seems to follow Javascript's patterns for type coercion. Some numbers can evaluate as octal numbers, and some can't. If a string starts with 0 and contains only numbers 0 through 7, then it is evaluated as octal. If the string starts with 0 and has any number above 7 (not octal), then it evaluates as decimal. It's not a mystery, it actually makes some sense even if octal in Javascript is not normally used.

On the rare occasion when you need to set file permissions from JS you will finally appreciate it :D

I hope I'm not going to spoil it by telling people to add t*=100; at the start to speed it up.

Nice game! I played the game and got bitten by the sharks when I was almost reaching the coin chest at the bottom of the sea.

u/rodrigo.siqueira thanks for playing it!! Yeah, the sharks can be a bit tough, but fortunately you don’t lose progress when you restart :D
